Introduction

WELCOME TO MDC

Off road caravanning is a rewarding way to travel and see our great country. Owning an MDC Caravan

will afford you the opportunity to travel to remote places and stay in comfort. It is the intention of

MDC for you to have the best possible owner experience and enjoy the great outdoors.

Terminology & Abbreviations

Tare Weight: The total weight of the trailer (load on tyres plus coupling load) with all options and fittings

as supplied by the manufacturer, with empty water tanks, excluding fluids not essential for operation on

public roads, and without luggage or personal effects.

ATM (Aggregate Trailer Mass) Rating: The total permissible mass of the Trailer. This includes the coupling

mass and whatever you add as payload (e.g. water, gas, luggage) up to the specified rating. The ATM Rating

must not be exceeded.

GTM (Gross Trailer Mass) Rating: The total permissible mass that can be supported by the wheels/ tyres of

the Trailer. This includes whatever you add as payload (e.g. water, gas, equipment, and luggage), but does not

include the mass supported by the tow vehicle. The GTM Rating must not be exceeded.

Caravans for illustration purposes only.

Terminology & Abbreviations

Ball Weight: The downward load exerted on the tow point of the vehicle by the trailer.

GCM: (Gross Combination Mass): This is the total allowable combined mass of tow vehicle and trailer as

determined by the tow vehicle manufacturer.

Camber: Camber angle is the measure in degrees of the difference between the wheel’s vertical alignment

perpendicular to the surface. If a wheel is perfectly perpendicular to the surface, its camber would be 0

degrees. Camber is described as negative when the top of the tyre begins to tilt inward towards the

chassis rail.

Toe In/out: Negative toe, or toe out, is the front of the wheel pointing away from the centerline of the vehicle.

Positive toe, or toe in, is the front of the wheel pointing towards the centerline of the vehicle.

Toe can be measured in linear units, at the front or rear of the tyre, or as an angular deflection. In the case of

MDC products, the “toe in” is measured in millimeters at the front of the tyre from the chassis rail.

Tow vehicle and Trailer Compatibility

Your tow vehicle manufacturer has applied a maximum towing capacity to the vehicle which is the Aggregate

Trailer Mass (ATM) and a maximum Gross Combination Mass (GCM). These specifications MUST NOT be

exceeded. It is your responsibility to know, understand and follow these specifications. Vehicle manufacturers

may also specify or recommend “Weight Distribution Bars” when towing under certain conditions. You MUST

ensure this is compatible with the vehicle and trailer combination.

DANGER

DANGER – Exceeding manufacturer weight and combination limits can result in loss

of control leading to death or serious injury. Your tow vehicle and hitch must be rated

for the Gross Vehicle Weight of the trailer.

Safety Information

Before using this product, you should read this manual, and those manuals supplied by component

manufacturers applicable to this product.

This manual is supplied as a reference to required maintenance of the product. Failure to use and maintain the

product in accordance with what is outlined in this manual may affect your warranty.

Incorrect and/or insufficient maintenance may cause product failure resulting in property loss, damage or injury

or death. Maintenance intervals are critical for normal use, extreme use may require shorter or additional

maintenance intervals.

Manual content does not imply, express or other any warranty, the owner should read the limited warranty terms

included in this booklet.

MDC does not cover damage due to unauthorised modifications, misuse, abuse, incorrect assembly, improper and

irregular maintenance or accident or collision.

Before using this product, you should be certain your tow vehicle is suitably rated and equipped to tow the

product safely and legally. The trailer and vehicle pairing must we within the safe “Maximum Towing Capacity,”

“Ball Weight Capacity” and “Gross Combination Mass” as stated by the vehicle manufacturer.

This caravan is fitted with electric brakes and a “Breakaway System.” Requirements for breakaway systems can

vary from state to state. It is mandatory to supply a maintenance charge to the breakaway battery source while

driving. You MUST ensure this capability is fitted to your vehicle. The maintenance charge is supplied to the

caravan via the Anderson plug on the drawbar.

BALL LOADING (DOWNWARD LOAD ON TOW HITCH) MUST NOT EXCEED 350KG

OR THE MAXIMUM ALLOWABLE LOAD BY THE VEHICLE MANUFACTURER OR TOW BAR RATING, WHICH

EVER IS THE LOWEST. Exceeding these limits may result in an accident causing serious injury or death and/or

property damage.

It is important to load your caravan correctly to distribute weight evenly and achieve a suitable ball weight

load and prevent loading in a manner that can cause a Caravan to sway and/or roll excessively left and

right. The industry optimum ball weight on a caravan is between 9 and 11% of the total Caravan weight.

MDC Caravans fit into this category and 10% should be used as the starting point.

Modifications to The Product

Gas Systems

The installed gas system on this product is an approved and certified installation. Any changes,

modifications or adjustment may render the system non-compliant and dangerous. Market Direct Group

Pty Ltd does not condone, recommend, or otherwise consent to any modifications, adjustment, addition or

Achieving a Safe Towing Combination

Ensuring a camper or caravan is safe and easy to tow is generally an easy thing to achieve, this doesn’t mean it’s

always the case and sometimes, a vehicle and trailer combination may need some tweaking to make it ideal. There

are a number of aspects that need to be correct in order to maximise towing safety and handling. It is important

to use this information in conjunction with the maximum weight limits applied by your tow vehicle’s manufacturer

as well as ensuring you stay within the maximum specified ratings of your caravan or camper. These can be found

in the vehicle’s owner manual. This summary will address the main aspects, these aspects include, but may not be

limited to the items listed in the following diagram:

Trailer Tyre Pressures

Tyre pressures have a large effect on the handling and performance of any vehicle, be it a towed vehicle or

motorized. The tyre pressure on your camper or caravan will indeed be a major contribution to how well it tows

and resists instability. Due to how much a camper or caravan may vary in weight depending on the cargo (as much

as 1600kg to 3000kg in the MDC range) it is important to have your tyres at the pressure recommended by the

trailer manufacturer, for the actual weight of the trailer when loaded. You should follow the tyre pressure guide in

this manual for on road/highway tyre pressures.

Tow Vehicle Tyre Pressures

Equally as important as trailer tyre pressure is the tyre pressures in your tow vehicle. The added weight of the

trailer ball weight should be factored into calculating the tyre pressures in the rear of the car. What should also be

factored in is the effect the distance of the hitch from the axles plays in leverage. A load on the tow bar of 250kg

may well have the effect of 300kg or more on the vehicles rear tyres meaning additional pressure must be

applied. This will limit sidewall flex and sideways movement of the rear of the vehicle, limiting unwanted

movement that can cause instability in the trailer.

www.marketdirect.com.au

I

Ph: 1300 494 494 I Contents 13

Ball (Coupling) Weight

The ratio of overall weight of the trailer to the weight exhibited on the tow ball or coupling

is an extremely important aspect of making a trailer handle correctly when towed.

Generally, the ball or tongue weight allowed by most vehicle manufacturers is 10% of the

maximum towing capacity. Given this ratio, the caravan industry builds campers and

caravans with this in mind. When loading your MDC caravan, you should have a target ball

or coupling weight of 10% or slightly higher to ensure the weight balance is at an ideal

starting point. This figure should not be a guess, you should weigh your caravan with its

normal load when travelling and use a ball weight scale to achieve the desires ball weight.

These are an inexpensive item that will help you get the weight balance right when you

load up for your trip.

Load Placement

Where you place the items in your trailer will affect how it behaves. Loading too much weight in the extremities

of the trailer can have a very bad effect. MDC owner manuals have a loading guide to assist in this area. By

following the guide and ball weight recommendations you’ll achieve the best possible result. Use the load

placement guide in this manual as a reference for packing your caravan.

Trailer Level

The height of your hitch in respect to the level of the trailer will change the handling while being towed. The best

practice with your MDC trailer is when loaded and hitched to the vehicle, the drawbar is NO higher than level.

Ideally you should look to have the drawbar slightly lower than level between 0 and 50mm. Higher than level or

too low will have an adverse effect on how the trailer tows.

www.marketdirect.com.au

I

Ph: 1300 494 494 I Contents 14

Hitch Movement

Most modern tow bars have an adjustable screw fitted to the hitch receiver that can be used to stop the hitch

insert from rattling. Unfortunately this is not a sure fire way to limit sideways movement that can affect how well

your trailer tows. Hitch movement from side to side can cause sway and when combined with a tow vehicle that

has a greater distance between the rear axle centre and the hitch point, this affect can cause serious sway issues.

Combine this with poor tyre pressures on the tow vehicle and you have a recipe for disaster.

If there is excess play in the hitch and hitch receiver, you may need to place shims either side of the insert to limit

the movement. Shims are commercially available such as the pack below.

Vehicle Squat

When the back of a vehicle squats due to cargo and/or ball weight of the trailer, the handling of the tow vehicle

can be changed to its detriment. Vagueness in steering, poor toe, camber, and caster settings due to reduced

front suspension load, reduced brake and tyre grip are often the result. All this in turn can result in a poorly

handling towing combination. The best way to rectify this is upgrading the tow vehicle suspension to be suitable

for the weights being experienced. Some vehicle manufacturers recommend Weight Distribution Hitches (WDH),

this will be outlined in the vehicle owner manual and should be considered. You should also consult with the

trailer manufacturer if this is an appropriate fitment to the trailer. The WDH should NOT be used in off road

operation as it will NOT meet the required articulation that will be experienced. To better setup your tow vehicle

suspension, it’s best to consult a suspension expert experienced with towing requirements.

Maximum Weight Limits

The following is an outline of the ratings that will be specified by the manufacturer of your vehicle and the

camper/caravan manufacturer. These MUST be followed in conjunction with previously mentioned criteria for

safe handling. None of the maximum ratings may be exceeded.

ATM (Aggregate Trailer Mass)

This limit is specified by the trailer manufacturer and must NOT be exceeded under any circumstances. The ATM

is the full weight of the loaded trailer including ball (coupling) mass.

Vehicle GVM (Gross Vehicle Mass)

This is the loaded weight including fuel, passengers, cargo, and ball (coupling) mass of the attached trailer on the

tow vehicle.

Axle Load

This is the maximum load on an axle specified by the tow vehicle manufacturer. It is possible to have your vehicle

and trailer within ATM, GVM and GCM load limits but above the axle load limit specified. Be sure that this is not

exceeded.

www.marketdirect.com.au

I

Ph: 1300 494 494 I Contents 16

GCM (Gross Combination Mass)

GCM is the maximum combined load of the tow vehicle and trailer, as specified by the tow vehicle manufacturer.

Never exceed this maximum weight limit.

Summary

The above will assist in tuning or trouble shooting handling problems with your towing combination but are not

the sole influences. Other items for consideration are:

• Wheel alignment on both vehicle and trailer.

• Wear and tear on:

- Suspension bushes

- Shock absorbers

- Springs

- Tyres

• Tow vehicle tyre size (Oversize tyres)

• Extended hitches

• Distance between axle centre and hitch point

• Tow vehicle accessories (Weight distribution)

• Real life tow vehicle capability (Not all vehicles are created equal)

The purpose of this information is to help you to do a self-assessment and achieve a sound towing combination. If

you are not confident you can achieve this, you should consult an expert to assist.

If you require assistance from MDC, call 1300 494494 option 3 and speak to our customer service department.

Towing Mirrors

Depending on the width of your car mirrors versus the overall width of your camper or caravan, you may

be required to fit extended mirrors to your vehicle when towing. The illustration below shows the

minimum required field of vision through your vehicle’s mirrors.

Note: Mirror extension attachments must be removed when not towing, fitted mirrors that extend must

also be retracted when now towing.

Jacking Your Caravan or Camper

Your trailer is fitted with purpose built jacking points supplied with a suitable jack. An appropriately rated bottle

jack is an acceptable alternative, however when using the jacking point beneath the trailing arm ensure the jack is

of a retracted height that will fit under the jacking point when the tyre is deflated. A suitably rated “High Lift” jack

may be used on the jacking points on the side of the body behind the wheels if fitted, provided it has the correct

positive engagement fitting to match the trailer. To ensure safe usage the following must be followed:

• The jack is to be used on level firm ground wherever possible.

• The wheels of the trailer should be chocked, and no person should remain inside the trailer whilst it is

being jacked.

• No person should place any portion of their body under a trailer that is supported by a jack.

• The trailer should be attached to the towing vehicle whilst being jacked.

• When performing maintenance ensure suitably rated jack stands are used – do not rely on the trailer

being supported by the jack.

Electrical Safety

Failure To Follow These Instructions May Result In Death Or Serious Injury!

When working with electrical equipment or lithium batteries, have someone nearby in case of an

emergency.

Study and follow all the manufacturer’s specific precautions when using and servicing the battery

and connected appliances.

Wear eye protection and gloves.

Keep the unit away from moist or damp areas.

Avoid dropping any metal tool or object on the battery. Doing so could create a spark or short

circuit which goes through the battery or another electrical tool that may create an explosion.

Shock Hazard! Keep Away From Children

Avoid moisture. Never expose the unit to snow, water, etc.

The inverter Unit provides 230 VAC, treating the AC output socket the same as regular wall AC

sockets at home.

Read and understand the information in the appliance manuals before operating this equipment.

The 240v electrical system in your caravan has been certified by a trade qualified person. Under no circumstances

should an unqualified person interfere with, modify, or repair this system. An RCD safety device is fitted to this

for your safety.

• Always use a 15amp lead to connect to mains power.

• Do not modify the earth pin to accommodate a lesser lead.

• When connecting to 10amp mains, always use an approved adapter.

• Never coil power leads when in use. Lay the lead out in lengths in a safe manner that prevents creating a trip

hazard.

Vehicle Electrical Requirements

Correct Vehicle Wiring for MDC Caravans

To comply with national laws on breakaway systems, you must supply a maintenance charge to the

battery/batteries that power the system should it be activated. In all MDC products, the breakaway is powered by

the house batteries in the caravan. For this purpose and Anderson plug connection is fitted to all MDC caravans

on the drawbar. Your vehicle will need to be fitted with a power supply to a 50 amp Anderson plug near the

towbar so the trailer can be connected. The vehicle only needs to supply power while it is running so a voltage

sensitive relay or switching device may be used to protect the start battery when the car engine is stopped.

Plug Type – 12 Pin Flat (Not Negotiable)

Charging Camper/Caravan While Driving

Plug Type – 50 amp Anderson Plug.

Vehicle with or without smart alternator:

The Anderson plug can be connected to the start battery on the vehicle and should include the following to

protect the start battery.

1. 50amp relay to stop power supply when vehicle is not running.

2. 50amp fuse or circuit breaker at the battery

Notes: The Projecta IDC25L DC to DC controller fitted in your MDC trailer is programmed to favour the solar

panel input exclusively until it drops below a threshold voltage input. By providing accessory power to the

number 12 pin, the trigger for the IDC25L will be set off to take power from both the Anderson plug and the solar

panels. It will also trigger the IDC25L to activate the vehicle’s ECU to make the alternator provide power to fully

charge the multiple batteries in your Caravan.
